Description

Technical Field

[0001] The present invention relates to the technical field of partial discharge testers, and particularly to a 6KV-110KV fully intelligent partial discharge tester. Background Art

[0002] The partial discharge tester is a new type of instrument developed and produced, which adopts advanced anti-interference components and a unique gate display circuit, and has four high-frequency elliptical scans. It is suitable for the type and factory acceptance tests of high-voltage products, the research and development tests of new products, and the quantitative tests of partial discharges of motors, transformers, cables, bushings, capacitors, transformers, lightning arresters, switches and other high-voltage electrical appliances. It can be used on-site by manufacturers, research departments and power departments. Although the existing testers for 6KV-110KV partial discharge testing have many testing effects, there are still deficiencies.

[0003] When the existing line partial discharge tester is used for 6KV-110KV partial discharge testing outdoors, due to the strong light irradiation from the outside, it may be difficult for the staff to accurately read the data displayed on the tester display screen, that is, the obtained data is inaccurate, resulting in the inability to implement subsequent measures normally.

[0004] Therefore, we propose a 6KV-110KV fully intelligent partial discharge tester to solve the problems raised above. Summary of the Invention

[0005] The purpose of the present invention is to provide a 6KV-110KV fully intelligent partial discharge tester. When the tester body is used under strong outdoor light, first turn on the first switch and turn off the second switch. Then, the probe of the photoelectric sensor senses the strong light, and then converts the sensed optical signal into an electrical signal and transmits it to the single-chip microcomputer. The single-chip microcomputer will compare the received data with the internally stored data, and then issue an instruction to start the forward and reverse low-speed motors. At this time, the started forward and reverse low-speed motors will directly drive the sunshade to move through the cooperation of the threaded rod, T-shaped block, connecting block and sliding hole. The moving sunshade will also drive the second concave block, buffer pad and second magnet to move. When the connecting block disengages from the threaded rod, the distance between the first magnet and the second magnet just meets the magnetic force range. At this time, under the action of the magnetic principle of opposite poles attracting, the second magnet will drive the sunshade to move again through the second concave block until the first magnet and the second magnet are magnetically connected together, that is, the automatic release of the sunshade is completed. That is, the sunshade can block the strong light from irradiating the tester display screen.

Two T-shaped blocks are fixed at the top of the sunshade plate, and the top ends of the two T-shaped blocks are respectively slidably connected inside the two sliding holes. Buffer pads are adhesively connected to the front surfaces of the two T-shaped blocks. The output end of the forward and reverse low-speed motor is provided with a threaded rod, and the front surface of the threaded rod threadedly penetrates through the rear surface of the connecting block. A plurality of mounting seats are fixed on the inner wall of the placement groove, and each mounting seat is connected to the transparent double-hole cover plate by bolts.

[0007] Preferably, a protective shell is provided at the top of the tester body. A plurality of first hand-tightening screws threadedly penetrate through the top of the protective shell, and one end of each first hand-tightening screw is threadedly connected to the top of the tester body.

[0008] Preferably, a placement box is fixed on the top inner wall of the protective shell, and a drying block is arranged inside the placement box.

[0009] Preferably, a plurality of air outlet holes are equidistantly distributed and opened at the bottom of the inner wall of the placement box, and a box cover plug is installed at the opening end of the placement box.

[0011] Preferably, two threaded grooves are opened at the top of the inner wall of each rectangular groove, and sliding grooves are opened on both sides of the inner wall of each rectangular groove.

[0012] Preferably, third concave blocks are rotatably connected to the outer surfaces of the two connecting rods, and rectangular columns are movably sleeved inside both of the two third concave blocks.

[0013] Preferably, second hand-tightening screws threadedly penetrate through the bottoms of the two third concave blocks, and anti-slip pads are adhesively connected to the rear surfaces of the two rectangular columns.

[0014] Preferably, the four chutes are divided into two groups, and sliders are slidably connected between the interiors of each group of chutes.

[0015] Preferably, L-shaped blocks are fixed to the rear surfaces of the two sliders, and the two L-shaped blocks are respectively slidably connected inside the two rectangular grooves. Third hand-tightening screws threadedly penetrate through the tops of the inner walls of the two L-shaped blocks. The four threaded grooves are divided into two groups, and one end of each third hand-tightening screw is respectively threadedly connected inside one of the threaded grooves in each group.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. When the tester body is used under strong outdoor light, in order to ensure that the test data displayed on the display screen of the tester can be accurately observed, first directly turn on the first switch and turn off the second switch. Then, the photoelectric sensor will start to work, and the probe of the photoelectric sensor will sense the strong light. After that, the photoelectric sensor will convert the sensed optical signal into an electrical signal and transmit it to the single-chip microcomputer through a wire. The single-chip microcomputer that receives the data will compare the data with the data stored internally, and then issue an instruction. When the value transmitted to the internal of the single-chip microcomputer is less than the value stored internally in the single-chip microcomputer, the single-chip microcomputer will not issue an instruction to start the forward and reverse low-speed motors. When the value transmitted to the internal of the single-chip microcomputer is greater than the value stored internally in the single-chip microcomputer, an instruction will be issued to directly start the forward and reverse low-speed motors. The started forward and reverse low-speed motors will directly drive the threaded rod to rotate, and the rotating threaded rod will drive the sunshade to move horizontally under the cooperation of the T-shaped block, the connecting block, and the sliding hole. The moving sunshade will also drive the second concave block, the buffer pad, and the second magnet to move. When the connecting block disengages from the threaded rod, the distance between the first magnet and the second magnet just meets the magnetic force range of the two magnets. At this time, under the action of the magnetic principle of opposite poles attracting each other, the second magnet will drive the sunshade to move again through the second concave block until the first magnet and the second magnet are magnetically connected together, that is, the automatic release of the sunshade is completed. This method effectively solves the situation that strong light shines on the display screen of the tester and the staff cannot accurately read the measured value, that is, it ensures that the staff can take accurate measures for the values obtained from the 6KV-110KV partial discharge test of the circuit in the later stage.

[0018] 2. When the tester body is not in use, in order to prevent foreign objects from entering the inside of the placement groove, causing damage to some components inside the placement groove, and at the same time avoiding moisture inside the placement groove, directly put the drying block into the inside of the placement box at this time, then use the box cover plug to block the opening of the placement box, and then use the first hand-tightening screw to install the protective shell on the top of the tester body. At this time, the drying block can directly maintain the dryness inside the placement groove through the cooperation of the air outlet hole and the sliding hole, and at the same time prevent foreign objects from entering the inside of the placement groove through the protective shell.

[0019] 3. When it is necessary to raise the position of the display screen of the tester body to facilitate the staff to observe the data, directly remove the third hand-tightening screw from the inside of one of the corresponding threaded grooves at this time, and then horizontally move the slider through the cooperation of the corresponding sliding groove. At this time, the moving slider will drive the corresponding L-shaped block and the third hand-tightening screw to move. When the slider moves to a suitable position, directly rotate the third concave block with the connecting rod as the rotation axis. At this time, the rotating third concave block will drive the corresponding rectangular column, anti-slip pad and the second hand-tightening screw to rotate. When the third concave block rotates to a vertical position, loosen the corresponding second hand-tightening screw at this time, move the rectangular column out of the inside of the third concave block by an appropriate distance, then tighten the second hand-tightening screw, and then move the slider again. At this time, the moving slider will drive the L-shaped block and the third hand-tightening screw to move. When the third hand-tightening screw moves to the position of the other threaded groove in the corresponding group, the slider just contacts the third concave block. At this time, directly thread the third hand-tightening screw into the inside of the other threaded groove in the group, that is, complete the fixation of the third concave block. Then repeat the above operation steps to fix the other third concave block as well. When both third concave blocks are fixed, the position of the display screen of the tester body will be raised at this time, which is convenient for the staff to observe. At the same time, the anti-slip pad can also improve the stability of the tester body after being placed. BRIEF DESCRIPTION OF THE DRAWINGS

Two T - shaped blocks 17 are fixed at the top of the sunshade 9, and the top ends of the two T - shaped blocks 17 are respectively slidably connected inside the two sliding holes 4. Buffer pads 18 are adhesively connected to the front surfaces of the two T - shaped blocks 17. The output end of the positive and negative low - speed motor 12 is installed with a threaded rod 19, and the front surface of the threaded rod 19 threadedly penetrates through the rear surface of the connecting block 14. A plurality of mounting seats 37 are fixed on the inner wall of the placement groove 2, and each mounting seat 37 is connected to the transparent double - hole cover plate 3 by bolts.

[0032] As shown in the figure, a protective case 20 is provided at the top of the tester body 1. A plurality of first hand - tightened screws 21 threadedly penetrate through the top of the protective case 20, and one end of each first hand - tightened screw 21 is threadedly connected to the top of the tester body 1. The protective case 20 can prevent foreign objects from entering the interior of the placement groove 2 through the sliding holes 4, that is, it can protect the components inside the placement groove 2. At the same time, under the action of the first hand - tightened screws 21, the protective case 20 can be tightly fixed on the top of the tester body 1.

[0033] As shown in the figure, a placement box 22 is fixed on the top inner wall of the protective case 20. A drying block 23 is arranged inside the placement box 22. It is convenient for the drying block 23 to ensure the dryness inside the placement groove 2 through the cooperation of the sliding holes 4 and the air outlet holes 24. At the same time, under the action of the placement box 22, it can be used to hold the drying block 23.

[0034] As shown in the figure, a plurality of air outlet holes 24 are equidistantly distributed and opened at the bottom of the inner wall of the placement box 22. A box - cover plug 25 is installed at the opening end of the placement box 22. It is convenient that under the action of the box - cover plug 25, the drying block 23 can be prevented from moving out of the interior of the placement box 22.

[0035] As shown in the figure, two symmetric rectangular grooves 26 are formed at the bottom of the tester body 1. Connecting rods 27 are fixed between the two sides of the inner wall of each rectangular groove 26, facilitating the rotation of the third concave block 30 from the inside of the rectangular groove 26 around a point under the action of the connecting rods 27.

[0036] As shown in the figure, two threaded grooves 28 are formed at the top of the inner wall of each rectangular groove 26, and sliding grooves 29 are formed on both sides of the inner wall of each rectangular groove 26, facilitating the horizontal movement of the slider 34 driving the L-shaped block 35 inside the rectangular groove 26 under the action of the sliding grooves 29.

[0037] As shown in the figure, third concave blocks 30 are rotatably connected to the outer surfaces of the two connecting rods 27, and rectangular columns 31 are movably sleeved inside the two third concave blocks 30. With the cooperation of the rectangular columns 31, the third concave blocks 30 and the second hand-tightening screws 32, the display screen of the tester body 1 can be positioned at any height.

[0038] As shown in the figure, second hand-tightening screws 32 are threadedly penetrated through the bottoms of the two third concave blocks 30, and anti-slip pads 33 are adhesively connected to the rear surfaces of the two rectangular columns 31, facilitating the tight fixation of the moved rectangular columns 31 inside the third concave blocks 30 under the action of the second hand-tightening screws 32. At the same time, under the action of the anti-slip pads 33, the stability of the tester body 1 placed in a horizontal position can be improved.

[0039] As shown in the figure, the four sliding grooves 29 are divided into two groups, and sliders 34 are slidably connected between the inner parts of each group of sliding grooves 29, facilitating the prevention of the rotation of the third concave block 30 under the cooperation of the sliders 34, the third hand-tightening screws 36, the threaded grooves 28 and the L-shaped blocks 35.

[0040] As shown in the figure, L-shaped blocks 35 are fixed to the rear surfaces of the two sliders 34, and the two L-shaped blocks 35 are respectively slidably connected inside the two rectangular grooves 26. Third hand-tightening screws 36 are threadedly penetrated through the tops of the inner walls of the two L-shaped blocks 35. The four threaded grooves 28 are divided into two groups, and one end of each third hand-tightening screw 36 is threadedly connected to one of the threaded grooves 28 in each group, facilitating the prevention of the movement of the L-shaped blocks 35 under the cooperation of the third hand-tightening screws 36 and the threaded grooves 28.

[0041] The effect achieved by the entire mechanism is as follows: When the tester body 1 needs to be used outdoors and the outdoor strong light is relatively strong, first connect the tester body 1 to an external power supply, and directly use the tester body 1 to test the partial discharge position of the line with voltages ranging from 6KV to 110KV. The data obtained from the test will be directly displayed on the display screen of the tester body 1. At this time, in order to ensure that the data of the partial discharge test of the line with voltages ranging from 6KV to 110KV by the tester body 1 can be accurately observed in a strong light environment, directly turn on the first switch 7 and turn off the second switch 8. At this time, the first switch 7 that is activated will cause the photoelectric sensor 5 forming an energized circuit to start working. The photoelectric sensor 5 that starts working at this time will directly use the probe on it to sense the external strong light. Then, the photoelectric sensor 5 will convert the sensed optical signal into an electrical signal and transmit it to the single-chip microcomputer 6 through a wire. At this time, the single-chip microcomputer 6 that receives the data will compare it with the data values stored in its internal memory. When the data value transmitted to the internal memory of the single-chip microcomputer 6 is less than the data value stored in the internal memory of the single-chip microcomputer 6, the single-chip microcomputer 6 will not issue an instruction to start the forward and reverse low-speed motor 12. When the data value transmitted to the internal memory of the single-chip microcomputer 6 is greater than the data value stored in the internal memory of the single-chip microcomputer 6, the single-chip microcomputer 6 will directly issue a start instruction to the forward and reverse low-speed motor 12. Then, the forward and reverse low-speed motor 12 starts. At this time, the forward and reverse low-speed motor 12 that starts rotates in the forward direction. The forward and reverse low-speed motor 12 that starts will directly drive the threaded rod 19 to rotate. The rotating threaded rod 19 will drive the sunshade 9 to move horizontally under the cooperation of the T-shaped block 17, the connecting block 14, and the sliding hole 4. The horizontally moving sunshade 9 will also drive the second concave block 15, the buffer pad 18, and the second magnet 16 to move. When the connecting block 14 disengages from the rotating threaded rod 19, at this time, the distance between the position of the second magnet 16 and the first magnet 11 just meets the magnetic force range of these two magnets. At this time, under the action of the magnetic principle of opposite poles attracting each other, the two second magnets 16 start to move in the direction of the first magnet 11. The two moving second magnets 16 will drive the sunshade 9 to move again under the cooperation of the two second concave blocks 15. When the two first magnets 11 are magnetically docked with the two second magnets 16 respectively, the sunshade 9 completes the operation of automatically opening. At this time, the strong light irradiating on the tester body 1 is blocked by the sunshade 9. At this time, the staff can accurately and easily observe the data on the display screen of the tester body 1. When it is necessary to retract the sunshade 9, at this time, turn off the first switch 7 and turn on the second switch 8. At this time, the second switch 8 that is activated will cause the forward and reverse low-speed motor 12 forming a circuit to start. At the same time, adjust the rotation direction of the forward and reverse low-speed motor 12 to reverse. At this time, the forward and reverse low-speed motor 12 will drive the threaded rod 19 to rotate in the reverse direction. Then, push the sunshade 9 into the placement groove 2. At this time, the moving sunshade 9 will, under the cooperation of the T-shaped block 17 and the sliding hole 4,Directly drive the second magnet 16, the second concave block 15, the connecting block 14 and the buffer pad 18 to move back. When the threaded hole of the connecting block 14 contacts the threaded rod 19 and is threaded with the threaded rod 19, the reversed threaded rod 19 will slowly drive the sunshade 9 to move back to its original position. When it is observed through the transparent double-hole cover plate 3 that the sunshade 9 has completed its reset, at this time, directly close the second switch 8. When the tester body 1 is not in use, in order to prevent foreign objects from entering the inside of the placement groove 2 through the sliding hole 4, avoid the situation where foreign objects damage some components inside the placement groove 2, and at the same time avoid the situation of moisture inside the placement groove 2, at this time, directly put the diatomaceous earth drying block 23 into the inside of the placement box 22, and use the box cover plug 25 to block the opening of the placement box 22. Then cover the protective shell 20 on the top of the tester body 1 and adjust its position. Then directly use the first hand-tightening screw 21 to stably install the protective shell 20 on the top of the tester body 1. At this time, the protective shell 20 can prevent foreign objects from entering the inside of the placement groove 2 through the sliding hole 4, and at the same time, the drying block 23 can keep the inside of the placement groove 2 dry through the cooperation of the air outlet hole 24 and the sliding hole 4. When it is necessary to increase the height of the display screen of the tester body 1 for the staff to observe, at this time, directly first thread out one of the third hand-tightening screws 36 from the inside of one of the corresponding threaded grooves 28 of a group. Then, through the cooperation of the corresponding set of sliding grooves 29, horizontally move the slider 34. At this time, the moving slider 34 will drive the corresponding L-shaped block 35 and the third hand-tightening screw 36 to slide inside the corresponding rectangular groove 26. When the slider 34 moves to a suitable position, at this time, directly rotate the third concave block 30 with the connecting rod 27 inside the rectangular groove 26 as the rotation axis. At this time, the rotating third concave block 30 will drive the corresponding rectangular column 31, the anti-slip pad 33 and the second hand-tightening screw 32 to rotate. When the third concave block 30 rotates to a vertical position, directly loosen the corresponding second hand-tightening screw 32, and then use the anti-slip pad 33 to drive the corresponding rectangular column 31 to move out of the inside of the third concave block 30, and the sum of the moving length and the length of the anti-slip pad 33 is the same as the distance required for the height increase of the display screen of the tester body 1. When the rectangular column 31 moves to a suitable position, at this time, directly tighten the second hand-tightening screw 32, and then move the slider 34 back again. At this time, the moving-back slider 34 will drive the L-shaped block 35 and the third hand-tightening screw 36 to move. When the third hand-tightening screw 36 moves to the position of the other threaded groove 28 of a group, the front surface of the slider 34 just contacts the third concave block 30. Then directly thread the third hand-tightening screw 36 into the inside of the other threaded groove 28 of the group. After that, repeat the above operation steps to fix the other third concave block 30 as well. When both third concave blocks 30 are fixed, the height of the display screen of the horizontally placed tester body 1 has been increased to a position that is suitable for the staff to observe with their eyes.,

[0042] Among them, a power-on circuit is formed by a first wire between the first switch 7, the forward and reverse low-speed motor 12, the single-chip microcomputer 6, the tester body 1, and the photoelectric sensor 5, while another circuit is formed by a second wire between the second switch 8, the forward and reverse low-speed motor 12, and the tester body 1.

[0043] Among them, the model of the forward and reverse low-speed motor 12 is 42GA775, the model of the single-chip microcomputer 6 is the MCP2515 CAN bus module, the model of the tester body 1 is HT-2007, and the model of the photoelectric sensor 5 is Z3N-TB22.
